Path of Exile

I just can't see playing until there is a pause feature for solo play.

That's not likely to be something that will ever happen. Monsters have a very wide movement range, so make sure you have cleared everything in the vicinity before leaving your character alone.

This. Unless the explosions are actually shaking the building or the blood is squirting out, I run back one to two screens of cleared area. This generally keeps my toon safe, only having been discovered anyways a couple times in all the time I've played, and I've left games "paused" for hours, even a couple days.
